Synopsis:
Featuring Gilbert Larose.

Larose has figured in a number of successful stories but in none so successful as The Poisoned Goblet, which tells of the efforts of a gang of men to kidnap the child of Lady Ardane. Larose takes a hand and immediately finds himself faced with one of the most puzzling and certainly one of the most hazardous cases of his career.
